FIELD

The present invention relates to collapsible structures generally andmore particularly to collapsible gazebos.

BACKGROUND

Collapsible gazebos may be used for many purposes such as providingshade or rain protection to allow for more enjoyable dining, resting orplaying while in the outdoors. Additionally, because the gazebos arecollapsible, the gazebos may be assembled and disassembled for use indifferent places, such as back yards or parks.

Conventional collapsible gazebos, however, can be difficult to assemble,detracting from the enjoyment of their use. For example, placing thecanopy (tarp) over the top of an assembled gazebo frame can be difficultbecause the portion of the gazebo frame that supports the canopy (canopysupport frame) is automatically deployed at the same time as the otherparts of the gazebo frame are deployed. Thus, the canopy support frameis too high for many people to reach and the canopy cannot be properlyplaced on its frame.

Therefore, a gazebo frame allowing for easier deployment is needed.

DETAILED DESCRIPTION

FIG. 1 is a perspective view showing the construction of a collapsiblegazebo frame 100, according to one embodiment of the present invention.The gazebo frame includes corner support members 112, scissor assemblies130, scissor assembly sliders 120, and a canopy support frame 152. Thecanopy support frame includes canopy frame sliders 125, canopy supportmembers 143, canopy frame joints 148, and canopy frame extenders 150.The canopy support members include outer canopy support members 145 andinner canopy support members 140. The gazebo frame may also include feet155 to and a canopy peak support member 160. The corner support membersmay include upper corner support members 110 and lower corner supportmembers 105.

The corner support members 112 rest on the surface of the ground. Thescissor assemblies 130 are each coupled to a different pair of cornersupport members and can be extended and retracted. Each of the scissorassembly sliders 120 are slidingly coupled a different corner supportmember as illustrated in FIGS. 1 and 1 a. The scissor assembly slidersare used to extend and retract the scissor assemblies coupled to theirrespective corner support members. That is, by sliding a scissorassembly slider along its corner support member, a user can extend andretract the respective scissor assemblies.

In the canopy support frame 152, the canopy support members 143 are eachcoupled to a different corner support member. The canopy frame joints148 which join the two portions of the canopy support members, the innercanopy support member 140 and the outer canopy support member 145, canbe placed in a locked position to make the canopy support frame rigid.Each canopy frame slider 125 is slidingly coupled to a different cornersupport member. Each canopy frame slider is also coupled to a differentcanopy support member by the canopy frame extenders 150 as illustratedin FIGS. 1 and 1 a. Upward movement of a given canopy frame slidercauses the respective canopy frame extender to apply force to therespective canopy frame joint, thereby bringing the inner canopy supportmember and the outer canopy support member into linear alignment. Theouter and inner canopy support members can be locked in linear alignmentby locking the canopy frame slider in an upward position.

The embodiment depicted in FIG. 1 shows the gazebo frame in a deployedor extended position. In deploying the gazebo frame from a collapsedposition, the canopy support frame 152 is deployed independently of thescissor assemblies 130. In one embodiment, the scissor assemblies aredeployed by sliding the scissor assembly sliders 120 in an upwarddirection along the respective corner support members 112. Sliding ofthe scissor assembly sliders in an upward direction causes the scissorassemblies to extend from the corner support members. In one aspect, thescissor assembly sliders may be locked in an upward position using, forexample, a push button latch in the corner support member. Locking thescissor assembly sliders in an upward position locks the scissorassemblies in an extended position, as shown in the embodiment depictedin FIG. 1. A further explanation of how the scissor assemblies aredeployed can be found in U.S. Pat. No. 5,944,040.

The canopy support frame 152 is deployed independently of the scissorassemblies 130 using the canopy frame sliders 125. That is, the canopyframe sliders operate independent of the scissor assembly sliders. Inone embodiment, upward movement of the canopy frame sliders causes thecanopy frame extenders to exert force on the outer canopy supportmembers. The force exerted on the outer canopy support members causesthe canopy frame joints to come into a ‘straight’ position. In thestraight position, the outer canopy support members are in linearalignment with respect to the inner canopy support members. In oneaspect, the canopy frame joints can be locked in the straight position.The locking of the canopy frame joints may be achieved by locking thecanopy frame sliders in an upward position using, for example, a lockmechanism such as a push button latch in the corner support member. Bylocking the canopy frame joints in a straight position, the canopysupport members provide a rigid support structure upon which a canopy ortarp may be placed. Furthermore, since the canopy support frame isdeployed independently of the scissor assemblies, the canopy may beplaced over the canopy support frame after the scissor assemblies areextended to form the sides of the deployed gazebo frame but before thecanopy support frame is deployed, elevating the peak of the gazebo frameand making it more difficult to place the canopy. Thus, the independentdeployment of the canopy support frame provides for easier assembly anddisassembly of the entire gazebo.

As stated above with respect to FIG. 1, the corner support members mayinclude upper corner support members and lower corner support members.In one aspect, the upper and lower corner support members aretelescoping with respect to each other, making the corner supportmembers expandable and collapsible. Furthermore, in one aspect thecorner support members are slanted inward toward the center of thegazebo frame when deployed to provide additional stability.Additionally, the feet 155 may be fixed to the bottom of the cornersupport members to rest on the surface of the ground and provideanchoring to the ground surface.

In another aspect, the canopy peak support member 160 providesadditional height and support to the peak of the canopy.

FIG. 2 is a perspective view showing the construction of a collapsiblegazebo frame 200, according to another embodiment of the presentinvention. The collapsible gazebo frame includes corner support members112, scissor assemblies 130, scissor assembly sliders 120, and a canopysupport frame 152. The canopy support frame includes canopy supportmembers 143, canopy frame joints 148, canopy frame sleeves 265 andcanopy frame extenders 250. The embodiment depicted in FIG. 2 providesan alternate mechanism for locking the canopy support frame in adeployed or extended position. The canopy frame sleeves 265 slidinglycouple to the canopy support members. The canopy frame sleeves can beslid around the canopy frame joints to lock the canopy support membersin a straight position. In one aspect, the canopy frame slidersdescribed with reference to FIG. 1 are used in conjunction with thecanopy frame sleeves described with reference to FIG. 2.

FIG. 3 is a detailed view showing a canopy frame sleeve 265, accordingto one embodiment of the invention. The canopy frame sleeves may be of ahollow ‘pipe-like’ construction or of any other construction suitable toslidingly couple to the canopy support members. In the embodiment ofFIG. 3, the canopy frame sleeve is depicted in a ‘locked’ position. Thatis, the canopy frame sleeve is slid around the canopy frame joint sothat the inner canopy support member and the outer canopy support memberare locked in a straight position. Furthermore, in the embodimentdepicted in FIG. 3, a sleeve stop 310 prevents the canopy frame sleevefrom sliding past the canopy frame joint. The sleeve stop may be ascrew, a bolt, welded metal or any other suitable construction.

FIG. 4 is a perspective view showing the construction of a collapsiblegazebo 400, according to another embodiment of the present invention.The collapsible gazebo frame 400 includes corner support members 112,scissor assemblies 130, scissor assembly sliders 120, and a canopysupport frame 152. The canopy support frame 152 includes canopy supportmembers 143, canopy frame joints 148, canopy support arms 455 and canopyframe extenders 450. The canopy support arms 455 couple to the canopyframe extenders 450 and to the scissor assemblies 130. Thus, the canopyframe extenders 450 do not directly couple to the scissor assemblysliders 120. The canopy support arms 455 may be pivotally connected tothe scissor assemblies 130 offset from the scissor assembly sliders 120,as illustrated. In one aspect, the canopy support arms 455 describedwith reference to FIG. 4 are used in conjunction with the canopy framesleeves described with reference to FIG. 2.

FIG. 5 is a detailed view showing a canopy support arm 455, according tothe embodiment depicted in FIG. 4. The embodiment depicted in FIG. 5depicts one of the canopy frame extenders 450 coupled to one of thecanopy support arms 455. The canopy support arm 455 is in turn coupledto one of the scissor assemblies 130. The canopy support arms 455 may bepivotally connected to the canopy frame extenders 450, as illustrated.The pivotal connection between the canopy support arm 455 and the canopyframe extender 450 and the pivotal connection between the canopy supportarm 455 and the scissor assembly 130 may collectively form an angle forextending the canopy frame extender 450 centrally in the expandedorientation, as illustrated in FIGS. 4 and 5. For example, the pivotalconnections may be non-parallel, such as one pivotal connection may beangularly offset by approximately forty-five degrees.

The present invention provides for easier assembly and disassembly of agazebo frame by simplifying the assembly and disassembly of the canopyand canopy support frame.
